The transistors, resistors, and diodes supplied in your kit are intended as replacements in case you find a failed component on your preamp.
The transistors supplied as shown in your photo are meant to replace a failed 2N3392 transistor. There are ten of these on your preamp.
These transistors are available at Mouser for 58 cents each. It is a low-voltage small-signal NPN silicon transistor in a TO-92 case.
There are lots of transistors that would work in this preamp as a replacement for the 2N3392. For instance, I have a lot of BC337-25 transistors on hand, and I bet they would work just great. BC337-25 has higher working voltage, higher max collector current, and similar hFE. But the BC337-25 transistor is arranged in the TO-92 case with a different pinout order.
Vintage Vibe has supplied you with a transistor that also has a pinout arrangement that is not the same as the 2N3392 original. This isn't a huge problem, because the Rhodes folks arranged the PC board layout before the advent of machine-stuffing production lines. So the board layout has the emitter, base, and collector solder pads arranged in a triangle (instead of straight-in-a-line). So all you have to do is carefully get the emitter, base, and collector inserted in the correct holes. The flat side on the transistor may be facing a different direction, but who cares?
When you hold the transistor so that the pins are going down, and the flat side is facing you (and you can read the markings on the transistor):
The pinout of the original 2N3392 transistor is Emitter, Collector, Base (E-C-B) from left to right.
Vintage Vibe claims that the replacement transistor is Emitter, Base, Collector (E-B-C) from left to right.
Can you read the markings on the transistor that Vintage Vibe sent you?
Maybe they substituted a 2N3904, which would have the Emitter, Base, Collector (E-B-C) from left to right.
In any case, to fix your preamp, you need to determine which component is problematic. In your case, since you had a fried lamp I would focus on components that could cause the lamp to blow, and components that would cause the tremolo oscillator to stop. So maybe one of the diodes or one of the two 2N3053 transistors died. The 2N3053 transistors are the larger ones in the TO-39 metal can. These cost $2.31 each at Mouser.
However, even if only one lamp is dead, and the oscillator is stopped, you should get audio out (as long as the other lamp is lit). This indicates that one of the 2N3392 transistors in the audio path is probably fried.
You should go ahead and install the replacement 150Ω resistors without even bothering to check the old ones. It is an easy swap.
But to find the real culprit, you need to get some trained diagnostic eyeballs, meter, and oscilloscope on that preamp.
